The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the land to the sky and back again. The Sun's heat provides energy to evaporate water from the Earth's surface (oceans, lakes, etc.). Plants also lose water to the air (this is called transpiration). The water vapor eventually condenses, forming tiny droplets in clouds. When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea). Some of the precipitation soaks into the ground. Some of the underground water is trapped between rock or clay layers; this is called groundwater. But most of the water flows downhill as runoff (above ground or underground), eventually returning to the seas as slightly salty water.

A borrower can get a mortgage from a bank, credit union, or other lender. Most lenders require the borrower to have a certain amount of money to use as a down payment. For example, if an individual wants to buy a home priced at $50,000 and the lender requires a down payment of $2,000, the individual will apply for a loan of $48,000 to pay for the difference. Payments for the loan are usually made monthly. The life of the mortgage can be 15, 20, 30, or even 40 years.
